Passing this 3rd party:

Borders of the Bronze:

richmond san rafael bridge toll plaza @ 580
estudillo @ 580
appian way @ 80
davis @ 880
caldecot @ 24
bay bridge toll plaza @ 80

Borders of the Aqua:
(Where it does not meet the Bronze)

580/205 split
crow canyon @ 580 (?)
dixon landing @ 880
scott creek @ 680

Ok, cool. So you're saying that answer to
I believe the Bronze extends all the way north of Alameda county into Richmond to the Richmond-San Rafael Bridge toll plaza, and then northeast into San Pablo. I'm trying to keep an eye on where the Bronze (Oakland) stops and the Maroon (Contra Costa) begins.
is that the boundary between Bronze and Maroon on I-80 is at Appian Way?

And the only unanswered question is whether the west boundary of the Aqua on 580 is at Crow Canyon?

I would also like to keep an eye on northwestern San Francisco, to see if the area of Hwy 1 (S.R. 1) / 19th Ave falls under the jurisdiction of the Pink (San Francisco) or Violet (Marin) offices.

Thanks!

Tonight I heard SF area receive a call for a disabled vehicle blocking a lane NB 1 just north of St. Francis Bl.

You have also expressed interest in knowing about SF working I-280 as far south as I-380. I have heard them going as far south as Larkspur. I believe Redwood City's area on I-280 stops at Trousdale.

Apparently not because I have seen Castro Valley units dispatched to Foothill Blvd in San Leandro on the CHP CAD.

I believe this is the boundary, though I am not positive. I have seen Contra Costa units (Maroon) dispatched to Appian numerous times, and heard Oakland dispatched to Richmond Pkwy, which is just south of Appian.

Thank you so much guys,

Given Wayne's info on the Bronze, I tried making a rough map using google. Let me know if the link works:

CHP Bronze - Google Maps

Ideally, I would eventually love to have (or make) a map of the Bay Area similar to the LA map with just the freeways and freeway exit boundaries. :)

Thanks again,

Inigo

It works, and it looks great, Inogo88.

BTW, I've been checking the GG Bridge all week in the filed incidents, and every call on the bridge in either direction has been listed as Marin. I haven't seen anything south of the bridge at all for either Marin or San Francisco until 280. I'm still waiting for something in the Presidio area, but either everyone is behaving or else the GGNRA Park Pollice or San Francisco PD has been taking care of it.

Sounds like fun. But keep in mind that their beats are not limited to just freeways and highways. For example, Napa has Silverado Trail and San Jose has many (or maybe all!) of the expressways.

West Valley Coverage into Malibu

I asked a source at the West Valley office about the coverage into Malibu. CHP covers all of Kanan, Malibu, Topanga and the unincorporated parts of PCH around Malibu. The city of Malibu is LASO typically. However he said that there is a great deal of overlap on their calls.

For the purpose of the map, I would continue to show the entire area as Teal. Calls would be handled by the West Valley office in and around Malibu anyway. I have personally seen them operating and moving through the city at times over the last few years.

The northern boundary would be the county line, Ventura-Purple and the southern boundary will likely be Topanga for Teal and then the West LA office-Pink would pick up coverage south of Topanga. There would be overlap between Sunset and Topanga, but it would normally be West LA's area to their south boundary.

Isn't Ventura on PURPLE? Seems to be missing from the map..
Yes, Ventura is on the Purple, and it's shown but with more of a teal-like shade. Yreka, at the top of the state, is also on the Purple and looks more purple-y. Any day now CHP is gonna run out of color names and have to start using the "Pink-Polka-Dot," "Black-and-White-Checkered" and of course "Blue-and-Gold-Striped" frequencies.

Too much time on my hands? :roll:

And CHP handles all public roads (and some off-highway incidents) in virtually all unincorporated areas of the state. I don't know the numbers, but my guess is that in square miles that's probably at least two or three times more land area that all the City PD's put together, but obviously mostly rural with much lower population and pop density numbers. Lots longer driving times though. About a year ago a CHP officer here in Humboldt put out an 11-99 ("needs immediate help") call and it was 45 minutes before the nearest unit, a Sheriff's Deputy, got to him. A downside to living, or working patrol, in such a beautiful area. Click:

I think it should say Crow Canyon @ 680 and I'll edit it.

I just pasted what was sent to me.
I have heard Dublin units dispatched to Diablo Rd on 680, which is two exits further north. But I cannot say that this is their normal area, so we should keep an eye (and ear!) on it.

landonjensen: I believe the map was made with Microsoft MapPoint. Nicely done, isn't it?!

Yes, Teal for Malibu and vicinity

I asked a source at the West Valley office about the coverage into Malibu.
I guess we were both on the same wavelength yesterday. I contacted CHP West L.A. office and LAPD West Traffic Division and a friend at Communications Div to find out their coverage areas.

You're correct about all of this:
CHP covers all of Kanan, Malibu, Topanga and the unincorporated parts of PCH around Malibu. The city of Malibu is LASO typically. However he said that there is a great deal of overlap on their calls.

For the purpose of the map, I would continue to show the entire area as Teal. Calls would be handled by the West Valley office in and around Malibu anyway. I have personally seen them operating and moving through the city at times over the last few years.

...until there.

I've got a correction for this little strip, though...
and then the West LA office--Pink would pick up coverage south of Topanga. There would be overlap between Sunset and Topanga, but it would normally be West LA's area to their south boundary.

West LA CHP doesn't come up PCH at all. Their western boundary is at the McClure Tunnel where PCH (SR1) dives under Ocean & Colorado Aves in Santa Monica... at what's essentially the west end of the Santa Monica Freeway. From there northward along the beach, it's Santa Monica PD's jurisdiction for a little a mile and a half to the Santa Monica/LA city line south of Chautauqua.. LAPD West Traffic Div then picks it up for the next 3¼ miles up to where the city ends at PCH and Coastline Drive in the high-rent Castellammare community.

None of the people I talked to knew for sure who handles the next little (just under a mile) piece of unincorporated area before the Malibu City Limits where LASD takes it over, but the guy at LAPD West Traffic said he thought that LASD covers it as part of their Malibu contract. The West LA CHP guy said it's definitely not theirs, but he didn't know if it was West Valley CHP's of the Sheriff's. Anyway it's something like this, and if I coded this thing right, clicking on my map should take you to a spiffy interactive Google map with a couple added details

Bottom line is what you said anyway. The whole area is best left as Teal, and LASD & CHP can worry about the wobblers.

Off-topic but kind of fun: for anyone who's driven thru that tunnel out to the beach at Santa Monica - like here, you can ride through its direct predecessor right out to the beach... 111 years ago at http://memory.loc.gov/mbrs/edmp/1627.mpg. Just watch out for CHP and SMPD.

CHP handles all traffic issues in unincorporated Sacramento County. Most of that is not rural, nor low density population. This repeats all over in places such as El Dorado Hills (which is also unincorporated).

Unfortunately with some exceptions, I do not see them patroling non-state roads nearly enough in these areas. For example, in Calaveras & Tuolumne counties you'll find them on highways 49 & 4 all the time, but virtually "never" on roads like Parrott's Ferry (which has just as much traffic).

OK. Then I would suggest updating the map and use the same "purple" color that's used elsewhere; like in Orange County, etc.. :)

Oh yea, and I love how in Napa the frequency designation is GRAPE !

The CHP in southern San Diego area is working off of the county RCS TRS? It maybe simulcast on vhf but I've never checked.

Did you find that they were willing to disclose information? I have hesitated from contacting my local offices for fear that they may think I am some kind of a nut. Do you have any tips on how to go about it?

I'd suggest calling/going in with a low-key attitude

Good question, and I was mildly but pleasantly surprised that the two officers I talked to - desk officers I presume, since I dialed their stations' business numbers listed online - were 100% friendly and businesslike. Not the slightest hint of any "attitude" whatsoever.

Neither one asked or even acted like they cared at all why I was asking. The CHP guy gave me the information right off the top of his head it seemed, as there was no delay at all. He admitted that since his office only covers as far as the McClure Tunnel, and he's never worked at West Valley, he had no idea about that area near Malibu.

The LAPD West Traffic guy, an Officer Castillo, started to answer about the Santa Monica side and then said, "Can I put you on hold a minute? I better go look at the map so I'm giving you the right information." About two or three minutes later he came on, apologized for the delay and gave me the info. When I then asked him about that mile or so between the L.A. City and Malibu City limits, he reply was something like, "Well, LAPD definitely doesn't handle it since it's outside the city, but I got a call up there a few years ago and I requested the CHP, but Malibu Sheriff showed up and it seems to me he said that they covered that part of PCH as part of their Malibu contract."

I didn't identify myself in any way, but started both conversations with "Hi, I've got a general-information type question I was wondering if you could help me with," and then just asked my question. I half expected them to ask if I was calling to report was an accident, so I phrased it that way. They caught my drift right away, I guess, but I'm sure if another call had come in (even though these were on the business lines) I would've been put on hold. Now that I think about it, that could have been part of the LAPD guy's delay.

The woman from LAPD Communications was an old co-worker, so that wasn't a problem at all, but since she works at the downtown dispatch center they seldom get calls on PCH. Only time that happens is when the Valley Dispatch Center's 9-1-1 lines are all busy, in which case their incoming 9-1-1's roll over directly downtown, and vice versa. Either center can dispatch calls to any division in the city, but they generally only dispatch the "other center's" calls when they're urgent (Code 2) or emergency (Code 3). Routine calls are entered into the CAD and are beamed to the correct RTO - RadioTelephone Operator/dispatcher.

After hanging around police people (including my brother, my sister, my wife, my ex-wife, and myself) for 40 years, I've learned that a low key approach almost always gets you a whole lot further. But I guess that goes with most any profession... they're more likely to respond to a "I don't know a whole lot about this, could you help me" attitude than to someone who comes across like "I know just about everything about your job except this ____". But I digress. As usual. I should change my username to "Off_Topic"

That little strip of unincorporated land between the L.A. City line and Malibu is a part of the Topanga State Park/state Beach property, so I don't know what effect that has on who handles traffic. I know Kenneth Hahn is a state park in the Ladera Heights area but the state contracts the services of the park to Los Angeles County Parks. Law enforcement is handled by L.A. County Police, so there may be some sort of similiar arrangement.
